Description

[Detailed description of the invention] [Industrial application field] This invention relates to a shutter in which slats formed with slits are connected in a daisy row and arranged in a row in a row, and each slat is electrically moved up and down. .

[Conventional technology]

Such a shutter is usually provided with an obstacle detection device to detect the presence of an obstacle below the lowermost slat (bottom slat).

The obstacle detection device includes a wireless system and a wired system.

In the wireless system, a band-shaped tape switch that closes electrically when an obstacle comes into contact with an obstacle is attached to the bottom of the bottom slat, and the ON signal of the tape switch is sent wirelessly to a fixedly provided control circuit or the like. is there.

On the other hand, in the wired system, an ON signal of a tape switch is sent to a control circuit by a wire through a conductive band provided on a guide rail or the like accommodating a slat. In some wired systems, a tape switch is attached directly along the guide rail, and a striker mechanism is provided for hitting the tape slat when the bottom slat is regulated to descend on the slat.

[Problems to be solved by the invention]

The wired method has the advantage that the operation is more reliable and the maintenance is easier than the wireless method. However, since the slats move up and down, electrical connection with a fixedly installed control circuit etc. becomes a problem. . In particular, in the case of a double-type shutter, etc., the middle rail which integrates the guide rail near the center and the center frame interposed therebetween is appropriately removed, so that the electrical connection and disconnection can be made accordingly. It must be able to be installed and removed by the user, and the connection and disconnection of the electrical connection must be very easy.

In addition, even if an obstacle is biased to one side of the slat and the slat is lowered only on this side, a detection device such as a striker must be equipped with a shutter to detect the presence of the obstacle. Must be provided on both sides.

The present invention is intended to solve such a problem. In short, the present invention proposes a shutter which can easily connect and disconnect the electrical connection associated with the installation and removal of the middle louver.

[Means for solving the problem]

In view of the above problems, this invention is based on a sensor of an obstacle detection device that is vertically arranged along the inner surface of the guide rail near the center by arranging pairs of slats constituting shutters on the guide rails at both ends. The electrical connection from the side member is integrated with the center guide rail and the center frame interposed therebetween, and is guided to a terminal fixed in a removable middle stand which is erected and provided above the slat. The electrical connection with the conductor from the control circuit of the obstacle detection device housed inside the box is guided to the terminal fixed to the box side member existing in the intermediate cubicle, and these two terminals are detachable. This is to provide a shutter that is brought into contact.

[Action]

By taking the above measures, the terminal connected to the sensor side member of the obstacle detection device is fixedly mounted in the middle cubicle, and the terminal of the control circuit side is connected to the box side member in the middle cubicle. Because it is fixed, attach the middle stake,
If removed, these terminals will be automatically removed.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 7 is a side cross-sectional view of the shutter. The shutter is a slat 4 having a substantially a hook member 2 having a slit 2a at an upper portion with a middle body portion 1 interposed therebetween, and a substantially square receiving member 3 at a lower portion. Is a constituent unit, and the hook body 2 and the receiving body 3 of each of the slats 4 are fitted to each other so as to be able to move up and down, bend and rotate, and are connected in a rosary. The connection of such slats 4 is wound around a winding drum 6 housed in a box 5 installed on the outside upper part of a rain shutter sash or the like so as to be rotatable forward and backward. The shutter is moved up and down by rotating the DC drive motor 7 forward and backward. At both ends of the slat 4, guide rails 8 are provided along the ascending / descending route.
It is moved up and down while it is inside. In a large portion of the opening, two sets of such a slat 4 and a guide rail 8 are arranged side by side to form a double shutter.

FIG. 1 is a side sectional view of a double shutter, and FIG. 2 is a plan sectional view. In such a shutter, a center frame 9 fills a space between guide rails 8 near the center, and these guide rails 8 and a center are used. An intermediate cubicle 10 is provided by integrating the frame 9 with screws or the like. The middle cubicle 10 is engaged with a hook-shaped box-side member 11 extending upward from the box 5 side, and is fixed by placing the lower part on the base 12, but operating the latch 13 provided at the lower part. By doing so, the fixation of the intermediate stanchion 10 and the base 12 is disengaged. That is, if the latch 13 is pulled up and the middle cubic 10 is pulled forward, the engagement with the upper box-side member 11 is released and the latch 13 can be removed forward.

FIG. 8 is a perspective view of the above-mentioned striker mechanism as an obstacle detecting device. Pins 14 and 15 are respectively provided on the sides of adjacent upper and lower slats 4 so that the pin 1
Links 17, 4 each with a contact plate 16 attached to one of the fronts at 4, 15
8 is pivoted, and the ends of the links 17 and 18 are crossed and pivotally supported by pins 19. As a result, if there is an obstacle below the bottom slat 4, the lowering of the obstacle is restricted, so that the distance between the upper and lower slats 4 is reduced,
The links 17 and 18 are broken, and the plate 16 projects forward. This plate 16
A sensor-side member 20 such as a tape switch which appears to be in an electrically conductive state when a predetermined pressure is applied at any point over the entire length is vertically provided on the inner surface of the front guide frame 8 (FIG. 2). When the plate 16 protrudes, this sensor side member
20 and is electrically conductive. When the sensor-side member 20 becomes conductive, the control is performed and the drive motor 7 is turned on.
An appropriate evasion operation such as stop of the operation is performed. Therefore, the electrical connection of the sensor-side member 20 must be connected to the control circuit, which is configured as shown in a perspective view in FIG.

First, the conductor 22 connected to the electrode of the sensor side member 20 is connected to the middle terminal 10 by using an insulator terminal
Lead to 23. Next, a conducting wire 24 connected to the control circuit 21 is guided to the terminal body 25 of the same insulating material attached to the box-side member 11 above the terminal body 23 in the middle cubic 10.

FIG. 4 is a cross-sectional view showing the details of both terminal bodies 23 and 25. The terminal body 23 on the side of the intermediate cubic 10 has a concave-shaped terminal 26 connected to the conducting wire 22 on the upper surface, and is fixed. The terminal body 25 on the side has a protruding terminal 27 which fits into the terminal 26 male and female.
27 is connected to the conductor 24. With this, both terminal bodies 2
When the terminals 3 and 25 face each other, the terminals 26 and 27 are in contact with each other. In order to complete the contact between the terminals 26 and 27,
The protruding terminal 27 is configured to be retractable within the terminal body 25, and is always urged in the protruding direction by a spring 28, and the magnets 29, 30 that are attracted to the opposing surfaces of the terminal bodies 23, 25 are attached. Keep it attached.

FIGS. 5 and 6 are cross-sectional views and plan views of another embodiment. In this example, the terminal 26 on the intermediate cubic 10 side has a sleeve 31 fixedly fitted to the terminal body 23, and the sleeve 31 is inserted into the sleeve 31. The wire terminal 26 is inserted, and the fixed terminal 27 is the same wire terminal 28 that comes into contact with the wire terminal 26 described above is inserted into the terminal body 25. By providing the springs 32 having both ends fixed to the sleeve 31 on the side of the intermediate cubicle 10 and the lower end of the terminal 26, the contact between the terminals 26 and 27 becomes more reliable by the tensile force.

As described above, when the intermediate cubicle 10 is set up, both terminals 26, 2
7 automatically contacts and electrically connects the sensor side member 20 and the control circuit, and when disconnected, the connection is naturally separated.

By the way, the above is the sensor side member 20 of the obstacle detection device.
As an example, the tape switch was hit with a striker mechanism.
It is needless to say that the present invention can be similarly applied to the case where the electric connection is conducted by the conductive band along the guide frame 8 and the electric connection is conducted on the lower surface of the guide frame 8.

[Effect of the invention]

As described above, the present invention is as described above, that is, the electrical connection between the sensor-side member 20 of the obstacle detection device which is attached and detached together with the intermediate cubicle 10 and the control circuit which is fixedly provided is intermediate. If the stand 10 is attached and detached, it will be automatically connected and disconnected accordingly, so anyone can easily do it. Therefore, even in the case of a double-type shutter in which the middle cubicle 10 may be removed, an inexpensive wired obstacle detection device that operates reliably and can be employed.
